are two uneven pale spots, followed outwardly by larger spots between 

 the dark sutures, and nearer the sides are two long curved pale lines ; 

 the lateral margins are broadly curved, greenish, bluntly rounded on the 

 anterior angles and almost rectangular on the basal angles, the posterior 

 margin is strongly curved, the sutures mostly black. Mesonotum piceous 

 black, sometimes tinged with rufous, the middle line pale greenish or 

 tawny, sometimes obsolete, on each side of this are two short, pale curved 

 lines, and still further outwards two longer pale curved lines, and the 

 lateral border usually pale, all of these lines are commonly covered with 

 whitish bloom ; flaps behind the crux broad luniform, pale greenish, 

 covered with bloom. Wing-covers sometimes tinged with whitish, mod- 

 erately ovately, but not acutely rounded at tip, costal vein flat, thick, pale 

 green, or testaceous, veins from base to end of middle series pale green, 

 apical series dark brown, the areoles mostly large and wide, the costal 

 areole short and wide, widest abont one-fourth from the apex, terminating 

 in an acute triangle, basal areole five-sided, longer than wide, com- 

 paratively long, areoles of the discoidal series long and wide, placed very 

 moderately oblique, slightly infuscated apieally, those of the apical series 

 wide and not very long, mostly acutely triangular at base, the basal 

 vein of the second areole strongly twice bent ; areoles of the wings 

 long, not much curved, widening apieally, the second-vein forking 

 widely towards the outer end. Underside of body greenish, tinged with 

 piceous, or fulvous tinged with green. Exterior valves of the male white 

 or pale greenish, sometimes dusky at base covering a little more than 

 one-half the length of the venter, each valve obliquely narrowing on the 

 inner border, and formed less obliquely on the outer border, overlapping 

 a little at base. Margins of the abdominal segments pale brownish. 

 Legs green or pale brownish, piceous at tip of tarsi, including the nails. 

 Length to tip of abdomen 27-30 mm. Width of base of pronotum 13-14 

 mm. Expanse of spread wings 98-100 mm. 



Seven specimens, three of which were males, have been in 

 my charge for examination. A pair of these were collected in 

 Arizona, not far from the Mexican border, by Dr. Edward 

 Palmer, and four others were sent to me by Mr. C. H. Tyler- 

 Townsend, from the vicinity of Las Cruces, New Mexico. 



The density of white bloom upon the surface of these in- 

 sects, particularly beneath, so hides the surface that the pat- 

 tern of marking is almost unrecognizable. 



The mesonotum is particularly convex and the almost con- 

 current high curve of the abdomen has the effect of causing 

 the wings to appear placed at an unusually low level. 



Upon clearing off the bloom from one of the specimens the 

 markings are disclosed as follows : tawny lines form two loops
